Bakuman 4: Slow-paced to the extent that only five or six chapters have been covered, but that wouldn't be an issue for non-manga readers. The art is still looking good/consistent and the hair colours are as eye-catching as ever, and there was an early look at the lead duo's 15-year-old rival that wasn't in the manga.
Yakumo 4: Still not a great series but the story-telling has improved, these last few episodes - the stories actually holding my interest a little now. But the cosplaying black overcoat-wearing villain, and his no doubt tragic past with the lead, is sure to lead to much eye-rolling. And Haruka is still an empty shell of a character; happy to be treated badly out of love.
Kami 4: The weakest episode so far; it focusing totally on the lead as he attempts to complete a bugged to hell game. The quality of the visuals/purty colours, as well as Kami's premise being unique, kept me entertained, but I hope more ero-game seduction tactics are being used on real 2D girls, next time around...
Imouto 4: Another great episode. Kirino's tsundere ways, and her older brother being happy to be treated like a doormat, are beginning to become irritating after all her big bro has done for her, while she's done sod all in return. However, how can I NOT like an anime where a carefully aimed ball-kick misses; resulting in the typical anime 'fall on female, with knee between legs and hand on boob' scene? Bitch-moe, FTW. And the story seems to be hotting up, next week, with Kirino's friend discovering the truth/possibly being another stealth otaku.
